Application inea retrmy 13,' 1891. sain No. 381,299. (No model.)

To a/ZZ whom t myconcern:

Be it known that I, RUSSELL BOWDEN, of Marblehead, county of Essex,State of Massachusetts, have invented an Improvement in Dinking-BlockSupports, of which the following description, in connection with theaccompanying drawings, is a specification, like letters and figures onthe drawings representing like parts.

In boot and shoe factories sides or pieces of leather are laid upondinking-blocks, with the end of the grain of the wood uppermost, and theleather is cut to shape by dies, which are struck by mallets, thecutting-edges of the dies entering or cutting into the grain of thewood. As the blocks become worn by the action of the dies the uppersurface is sawed or planed oif, and at each time that the upper surfaceis so sawed or planed off the height of the block is reduced, and hencesuitable means must be provided Jfor supporting the block so that itsupper surface will always remain ati-substantially the saine height. Inpractice this has been done by blocks or pieces of board and the likeplaced beneath the dinking-block, and such support is very unstable andcumbersome.

This invention has for its object to construct a suitable support forthe dinking-block,which is made adjustable to support the block at anyheight desired.

My invention consists in the combination of suitable side rails anduprights or posts at each end thereof, to which the said side rails areadj ustably connected.

Figure l shows in side elevation a dinkingblock and its supportembodying this invention; Fig. 2, a section of the parts shown in Fig'.l, taken on the dotted line @c 0c; and Fig. 3, a sectional detail of aportion of the uprights shown in Fig. 1, taken on the dotted line/y y.

The wooden dinking-block ct, with the end of the grain uppermost, restson cross-bars b b, mounted on parallel side rails c c, having tongues ortenons c at the ends, which enter grooves c2, formed in verticaluprights or posts d, there being four such uprights or posts, two ateach end of the side rails, and connected together by dowels 4. Theuprights or posts d are embraced by suitable clamps e, shown as of metaland of loop form, (see Fig. 1,) each clamp being pivotally connected tothe ends of the side rails c c, there being four such clamps, oneembracing each upright or post, and loosely connected to one end of aside rail. As represented at the right, Figi, the uprights or post-s elhave notches 2 at regular intervals apart, and the loop-like clamp e,embracing the said uprights or posts, enters one or another notch. Theloop-like clamp e is of suitable length to allow the side rail to whichit is connected to be moved vertically when the said clamp e. is in asubstantially horizontal position, and when the said clamp e engagesone. of the notches and the said rail is allowed to drop a shortdistance it will be held by the said clamp, as shown in Fig. l.

The uprights or posts d on opposite sides of the apparatus may havenotches, as 2, or, .in lieu of said notches, a suitable notched wedgedblock w may be provided, as shown, which is engaged by a loop-like clampe, and the weight of the side rails c c draws the looplike clamp againstthe wedge-block w and holds it firmly against the uprights or posts, sothat by this means the said side rails may be supported. i

As the dinking-block a is sawed or planed off and it is desired to raiseit the side rails c c are lifted and the loop-like clamps e therebystraightened or caused to assume substantially horizontal positions, andwhen in such position the side rails or one end thereof may be raisedand the clamp c caused` to engage a notch above it, or caused to engagethe Wedgeblock w at a higher point on the uprights or posts. It will beseen that the ends of the side rails maybe lifted independently, andthereby any corner of the block may be raised independently, if desired.

On the top side of the side rails c c a series4 of holes are formed,into which pins, as 5, may be placed to assist in holding the block dagainst lateral movement, and on the top side of the cross-bars b bholes are formed, into which pins 6 may be placed to assistin holdingthe block a against a movement forward or backward, and the cross-barsbr have on IOO ' tially as described, to adjust each end independently,the ends of the side rails moving in said grooves, substantially asdescribed.

2. The herein-described dinking-block snpport, consisting of side railshaving?` loop-like clampse pivoted thereto, and uprights orsupportsernbraced by said clamps, the uprights being held between theclamps and the ends of the side rails, and a sliding locking-wedge forone of said clamps, substantially as described.

3. The herein-described dinking-block support, consisting of` side railshaving pins, as described, and cross-bars placed on said side rails andalso having pins, as described, and uprights or posts to which said siderails are adjustably connected, substantially as described.

In testimony whereof I have 'signed my name to this specication in thepresence of two subscribing witnesses.
